Dossier evaluation

REACH requires EU companies manufacturing and importing chemicals to assess their chemicals and propose risk management measures. This assessment needs to be documented in a registration dossier which companies need to prepare and submit to ECHA. Information on properties and uses must be provided on all chemicals manufactured or imported in quantities of one tonne or more per year.

Examination of testing proposals

Registrants must submit a testing proposal if they intend to perform a new test listed in Annexes IX and X to REACH.

The aim of testing proposal examination is mainly to avoid unnecessary animal testing, especially when the testing involves the use of vertebrate animals. Registrants need to receive ECHA’s decision before they can perform any testing.

ECHA evaluates all testing proposals made by registrants.
